Updated the OpenGroup polling to run on a non-main thread
Updated the TSGroupModel to store moderatorIds as well as the adminIds (new endpoint is only going to give diffs)
Updated the BatchRequest to support json, base64 encoded strings and raw bytes for it's body
Replaced the 'lastMessageServerID' methods with 'OpenGroupSequenceNumber' methods (since we have swapped the property over)
Added an alert when banning fails (previously it would fail silently)
Fixed a bug where sent blinded messages were appearing as incoming messages
Fixed a bug where the OpenGroup infoUpdates wasn't getting decoded correctly
Fixed an issue where the ConversationVC wouldn't become the first responder again after the ban alerts disappeared
Fixed an issue where I'd incorrectly used the message 'seqNo' in place of the message server id
Fixed an issue where open group messages were setting their `sentTimestamp` to seconds instead of milliseconds for incoming messages
Updated the MessageSendJob to support V4 messages (V2 messages will be upgraded to V4 if they get re-encoded)
Renamed the Message+Destination from 'openGroup' & 'openGroupV2' to 'legacyOpenGroup' and 'openGroup'
Started plugging in more of the V4 APIs
Renamed a number of the V2 APIs to start with 'legacy'
Fixed a bug where sharing a text file was resulting in the entire contents being put into the message input field
Fixed a bug where sharing from within the app where the app was in dark mode but the device was in light mode would result in buggy UI
